I would guess it would be an order of magnitude faster to ingest data if you didn't have to go through text formats to do it.

This may be possible since Liblas has a las2ogr tool and GRASS uses ogr for vector input - seems there's an opportunity to script output from the former and pipe it as  input to v.in.ogr ?  Beyond my skills unfortunately ....
